Part of my problem is to mount said webcam to the scope. The lens opening is on the side and I attach it with elastic bands, but it is quite a thing to move it. Can I make a plastic tube, with one end glued to the webcam (over the opening) and the other end to slide into eyepiece holder? If so, how long should this tube be?  |

Tube needn't be too long ... so long as you can achive focus. If you can make the chip sit at a similar height to where a 4 or 6mm eye piece normally would, it should be focussable.

I remembered that I had an old damaged eyepiece (received it damaged back after lending it out). I can use the sliding tube of that and attach the webcam with Prestick. That will allow me to move it, to centre the image. Hope it's going to be long enough. Going to try it out now on a distant tower.  |

Not quite down so you can see the flag yet, but a big improvement over previous effort. Very difficult to focus. Will try next time without 2X Barlow lens. Very early morning tomorrow so can't do it now, but check this spot on the weekend.  |

Nugter weet. Ek weet nie eers of dit groot of klein is nie. Ek het maan in oogstuk gekry en toe webcam gekoppel, maar toe was fokus heeltemaal uit. Het toe op hiedie deel ge-eindig met scope se focuser. Probleem was dat dit heeltemal geblur het terwyl ek aan scope geraak het, so ek kon nie aanhou stel tot dit in focus was nie. Ek het nou op "SharpCap" software afgekom wat kan autofocus. Sal dit die naaweek probeer. Ek sit nou naby Polekwane. |

My scope se fokus werk hier as growwe fokus. Ek het fyn instelling nodig.

Behalwe fokus is die probleem om die voorwerp in beeld te hou. As ek deur die oogstuk kyk is die voorwep stil, maar hier kan gesien word dat die tracking nie 100% is nie.  |

Presiese tracking en 'n equatorial mount (of 'n vurk mount met 'n wedge) is net belangrik vir laaaang individuele exposures. Jou webcam lees 'n stroom van kort frames en stoor dit as 'n fliek. Registax sal dan kompenseer vir drift wat van frame tot frame plaasvind. Genugtig, ek moes maar in ingels geskryf het.
